Our team is building a cutting-edge communication platform for Taxi, Food, Lavka, Market, and Delivery services. Every day, the platform sends billions of communications to millions of users. We are currently at the stage of writing many new microservices, so you won't have to work with legacy code.

Our goals: * Improve efficiency: send the most relevant and non-intrusive communications using algorithms and ML models * Enhance stability: develop new functionality with guaranteed system stability, reliability, and scalability

Our product touches on different areas of development — you'll be able to specialize in narrow fields, such as highload, and learn new things.

Tasks awaiting you

Communication prioritization and filtering You will optimize interactions with each user, applying algorithms and machine learning to display the most relevant content. It's important to do this not just optimally, but also quickly.

Communication delivery and display You will work with high-load environments to maintain efficiency. To send billions of messages every day (that's tens of thousands of requests every second!), the system must be extremely reliable and scalable.

We expect you to

• Be proficient in classical algorithms and data structures
• Have worked with C++ or be willing to switch to it
• Be ready to seek out and make bold technical decisions
• Be familiar with modern DBMS: PostgreSQL, YDB
